Mathcad

Was using free trial and then my school put their license on my computer and now all my documents I was using on the free trial say file not supported. Need files urgently for deadline

A challenge from Facebook, and one of the (wrong) answers.   My solution is in the closed area.  Have some fun.

I would like some help to develop a loop in Mathcad that appends each intersection point between a piecewise linear curve and a set of straight lines, to the piecewise linear curve matrix. The attached Mathcad Prime 11 file contains the details and a fuller explanation of this request for assistance. 

I started my college years using Mathcad 11, and I still use it after two decades. And for many reasons: I know its plus and minus points (more plus than minus).Once upon a time, I could integrate it with Excel and other software.It is reliable overall: no crashes or file corruption.It saves space and memory: in 100Mb of HDD and a few dozen Mb of RAM, it does what other mammoth software (including the following versions of Mathcad, not to speak of Mathcad Prime) do.I always kept an eye on the PTC community to look at the reactions to Mathcad Prime's evolution. I think I am not alone in still using the Classic Mathcad (if not v.11, it will be v.15).  I am interested mainly in Calculus (so symbolic math solutions), Matrix Algebra Simulations, and a few Statistics. At the same time, I am not interested in integrating Mathcad to other PTC software.Is it worth moving to (or trying) Mathcad Prime v.10? Given the above interests, how is it compared to t

On one particular calculation, I get a red box"System Error: Item has already been added. Key in dictionary: "Key being added: " Anybody have any insight?

I've been using MathCAD Express 10.0.1.0 version now and tried to upgrade the software to version 11 yesterday. Tried to fill out the free trial form but never receive the download link even after a day. Could I get help how to upgrade the software but still stick to the free Express version?

I've been doing a bit of revamping my Mathcad Express worksheets to Mathcad Express 11.  As part of this activity, I've updated my library of timing functions to reflect the way I've been using them.    For example, timer1(f,a) used to return both f(a) and the time it took to evaluate f(a); now, it just returns the time taken, whilst timer1n(n,f,a) executes f(a) n times.   For those of you with prior versions of Mathcad, here are the timing function definitions:     Here is a good example of how writing recursive algorithms should be done with care, fib vs Fib.     And here's a graph showing just how much worse the difference in Fib's performance gets as its input argument n increases.     The timing functions are in the first Area in the attached Mathcad Express 11 worksheet (to make it easier to copy them to another worksheet or include them in a template).   The utility of such functions is also evinced in:   https://com

Hello Assuming you have a matrix defined, is it at all possible to use (part of) this matrix to create the choices available in a "Basic combo box"?More explanation:I use READEXCEL to read a table from an Excel file, and get a matrix with column headers in the first row, and some other identifier in the first column. Can I put this matrix into a combo box, so that the user can select the relevant row for further calculations?RegardsHallvard

How can I download the trial version of Mathcad Express? Im a University student, trying to download the program for one of my classes, but nothing happens after entering my data on this website: https://www.mathcad.com/en/try-and-buy/mathcad-express-free-download

Hello to everyone, I have a new laptop where I have already installed Mathcad Prime 11.00, but some of my old Mathcad 15 files still do not work well in Mathcad Prime when I convert them.I still have the Mathcad 15 package saved in my cloud, but I don't know how to make it work. What should I do to make it to work? regards,  Rogelio

My classmate registered for MathCad (trial subscription) but did not receive any emails from PTC/MathCad. Our professor insists that we use MathCad, but he cannot do homework because his registration never went through. Please advise.

My string library defines three different representations of a string, two of which should already be familar: the string and the vector of character codes. The third type is the vector of characters.   In the following, "str" indicates a string, "vec" indicates a vector of character codes, and "chr" represents a vector of characters. For example, chr2str indicates a conversion from a string to a vector of characters.   chr2str itself is relatively quick, even for long strings. chr2str0 has the limitation of hitting Mathcad's recursion depth limit. chr2str2's use of folding over concat, however, is proving somewhat slow once the string length increases to above about 20,000.   The challenge is to define a faster recursive variant of chr2str.     Where the dependencies are as shown below (except the timer functions, which are in an Area at the top of the attached Mathcad Express 11 worksheet).     Stuart

I'm using MathCAD 9.0.0.0. I laid our 2 sets of 3 equations. One set is using variables. The other set has the values plugged straight in. The set with the variables should equal the set with the values because the values are the same, but they don't and none of them equal the correct answer. What should happen is...Rx=Rx=-22Ry=Ry=211.5R=r=213My MathCAD program is written to follow this example...This is how my MathCAD program looks...Ignore the 25 degrees and the 75 degrees in the diagram. This is a homework problem altered to match the example problem so I can test to make sure it works before plugging in the values for the homework problem. Also, I'm interested in fixing the "values" problems Rx, Ry, and r. I only created those to figure out why my variable problems Rx, Ry, and R aren't working. Attached is my program. Thanks,    Brent 

I'm using MathCAD 9.0.0.0. I'm not sure why I'm getting the wrong answer. The calculation should be...R = 329.687 N...but I'm getting...R = 108695.156 NIs there something wrong with my settings? Thanks,    Brent 

Does anyone know why the attached issue is occurring? It seems that when you run units of feet, there is some kind of internal rounding error.

I'm using MathCAD 9.0.0.0. How can I use MathCAD to solve for theta? Below is the screen capture of what I have written so far. Attached is my MathCAD file. Thanks,        Brent 

Hello, I'm trying to draw 3D spline go through 5 points defined by matrix "a" .After defining matrix of x range, y and z, these three matrixes are not able to be combined by "augment" function.Are there any way to combine these three xyz matrixes? or any other way to plot xyz?  

I'm using MathCAD 9.0.0.0. Attached is my program. I need to find theta. Theta should equal 32.6 degrees. How can I get MathCAD to solve for theta? Thanks,      Brent 

Hello,I'm using a worksheet in Mathcad prime 11 with the pwrfit function to interpolate the curve of electronic components.Since I like working with units in Mathcad, I slightly modified the interpolation coefficients to include units.Solve this kind of equation, but with the interpolation VPROT = F(I). I is the resultMy goal is to solve a function that uses this interpolation. The solve function doesn't work, but I can find the solution for a single point using a solve block and the Find function.   Could you help me to solve the solve function 🙂 Thank youSee attached file.  

Hello community!I request your help with the following: I want to enter a matrix into a larger one.I’m working on assembling a global stiffness matrix of a structure (truss)I have defined the matrices of each element. The matrix of the element is 4x4, "i"= 1 to "n", n: number of elementsI have an auxiliary matrix that defines in each row the degrees of freedom associated with each element. For example row 1 contains the degrees of freedom of element 1 and so on. I named this matrix GDL  What I want is for Mathcad to grab the matrix of each element and place it in the global matrix at the positions corresponding to the columns and rows that indicate the row of the auxiliary matrix GDL. For example the stiffness matrix of element 3 must be placed in rows and columns numbers 1, 2,5 y 6 of the global matrix.I understand that once the correct routine is created I would have to use a FOR cycle to do it for each element. But at the moment I’m trying to test with only one element&nbs

I am currently using the free trial version (EXPRESS) of Mathcad Prime. After converting a file created with the old Mathcad using the "Input/Output" XMCD converter menu, I opened the converted file and tried to copy and paste a table from Excel into the original table, but it is not reflected. During the conversion, a message "To maintain the numerical results of the input table, the table has been converted into a matrix" was displayed. Is this the cause? Could you please tell me the reason and the solution?

The Mathcad functions matrix, CreateSpace and CreateMesh have a few limitations that led me to create alternatives.   One set of limitations is that the x (& y) ordinates they use are restricted to being linearly spaced (unless using a mapping function in CreateSpace and CreateMesh).  This often proved a nuisance, so (way back in Mathsoft Mathcad v11), I wrote replacements for them that allowed me more control over the x & y coordinates.   Secondly, Mathcad doesn't have a vector counterpart to the function matrix. A simple enough thing to implement.   And, bringing us up to date, CreateSpace and CreateMesh are Premium functions in Mathcad Prime, thus unavailable for Mathcad Express.   With the latter in mind, and noting CreateSpace's use in a recent thread, I thought I'd cobble together a worksheet showing one possible Express implementation of the functions vector, matrix, Vector, and Matrix (the latter two being replacements for CreateSpace and C

Hi everyone,I’m currently exploring how different PTC tools can be leveraged together and had a question regarding potential integration.Has anyone worked with or come across an integration between Mathcad and Windchill Risk and Reliability? Specifically, I’m interested in understanding:Whether there's any native integration or API-based connectivity between the two tools.If it’s possible to embed Mathcad calculations into risk models or reports generated within Windchill Risk and Reliability.Any best practices or workarounds for using outputs from Mathcad (e.g., failure rate calculations, stress analysis, etc.) to support risk and reliability assessments in Windchill.How such an integration (if available) could streamline risk analysis workflows or improve traceability.I’d really appreciate any insights, documentation references, or experiences you can share. Thanks in advance!

HelloI am looking for a way to access and override the content of headers without starting MathCad. This is required for our document management system - once the file is officially issued the document management system needs to override the date, title, etc. I do understand that MathCad files are zipped xml's and I could modify the values in the xml file but the header/footer text content does not seem to be available.  Thank you in advancedMichal
